Pot

ABSTRACT

The invention relates to a pot ( 80 ) having a multipart setup, the pot comprising an enveloping pot ( 83 ) and a product pot ( 81 ), which is received in the enveloping pot ( 83 ) and serves for receiving a lotion or the like, the enveloping pot and the product pot being made of the same or different materials, intersections being formed between the different components for separation purposes, the intersections being realised as detachable form-fit, substance-to-substance or force-fit connections.

The invention relates to a pot having a multipart setup, the pot comprising an enveloping pot and a product pot, which is received in the enveloping pot and serves for receiving a lotion or the like, the enveloping pot and the product pot being made of the same or different materials.

Pots of the type mentioned above are often realised as material hybrids, which means that the pots made of a plurality of components comprise components which consist of different materials. In the case of the pots mentioned above, the pots are mostly made of material hybrids or material mixes made of aluminium and plastic, meaning an effective recycling presumes separating the materials in particular in the case when the respective material portion exceeds a certain range. Separating the materials often proves time-consuming, in particular when separating the materials cannot be carried out economically means sacrificing the inferior or less valuable material to enable recycling the more valuable material portion. This can occur, for example, when pots, which have aluminium and plastic components, are molten for recycling purposes so that the material is separated in this case by burning or gasifying the plastic portion.

An extensive recycling of a pot made of several components becomes possible using two different approaches, for example, the pot of the first approach being designed such that the individual components can be easily separated from each other, while the second approach strives for a plastic portion as small as possible to limit the non-recyclable portion of the pot to a minimum when sacrificing plastic material.

The object of the present invention is therefore to propose a pot which enables a simplified recycling of the used materials and is distinguished by a particularly high portion of recyclable materials.

To attain this object, the pot according to the invention has the features of claim 1.

According to the invention, intersections are formed in the pot between the different components for separation purposes, the intersections being realised as detachable form-fit, substance-to-substance or force-fit connections so that the pot according to the invention does not have to be supplied to the recycling process as a whole unit, but instead the components can be separated before recycling takes place owing to the intersections for the subsequent supply of the components to different recycling methods or non-recyclable materials or materials which can only be recycled with great effort can be separated from the materials which are comparatively better suited for recycling, if applicable.

A possible separation of the components is deemed advantageous even if the material of only one component is to be recycled, i.e., to be shapelessly returned to state of the original material, whereas the other component is to be reused in its current form. In this case, the components can be made of the same material.

The pot according to the invention also makes it possible to reduce a material portion, e.g., a plastic portion, to a range as small possible, e.g., less than 10 percent, and to choose a uniform recycling method for the other components, in particular in the case when these materials consist of a uniform material, such as in particular aluminium.

In any case, the pot according to the invention consequently simplifies recycling the pot.

It is particularly advantageous if the pot comprises a pot collar, which connects the product pot to the enveloping pot, and a pot weight, which is disposed in a gap formed between the product pot and the enveloping pot, a first connection being formed between the product pot and the pot collar and a second connection being formed between the pot collar and the enveloping pot, allowing the option of producing an intricate pot made of different materials, which can be separated at defined connective positions, if required.

If the pot collar for forming the first connection is connected to an abutment edge of the product via an upper collar edge and supports itself on the pot weight, which is disposed in the enveloping pot, by its lower support edge, the pot weight itself can be used for connecting the components.

Preferably, the pot collar is connected to a connective edge, which is formed on the enveloping pot, via a ledge, which extends around the pot collar, for forming the second connection so that the connection can be produced as easily as possible.

It is particularly advantageous if a transition surface formed on the ledge is fully flush with an edge of the enveloping pot formed on the connective edge so that an aesthetic and uniform appearance is possible despite possibly present material intersections.

If the product pot is designed as an exchangeable pot, which is connected to the enveloping pot via a force-fit or form-fit connection, the product pot can be separated from the enveloping pot, if required, without requiring any particular effort.

It is particularly advantageous if the product pot comprises an inner pot, an outer pot and a pot collar connecting the inner pot to the outer pot, a first connection being provided between the pot collar and the inner pot and a second connection being provided between the pot collar and the outer pot.

Preferably, the product pot is received in an inner pot of the enveloping pot, which comprises a pot jacket and a pot bottom formed independently of the pot jacket, a first connection being provided between an upper edge of the inner pot and an upper opening edge of the pot jacket and a second connection being provided between a lower edge of the pot jacket and the pot bottom.

Designed in this manner, both the product pot and the enveloping pot each have an aesthetically pleasing exterior comprising an inner pot and an outer pot, the exterior remaining intact even if the product pot and the enveloping pot are used independently of each other.

If the pot connection is realised as a locking connection, which comprises a shape-elastic locking element disposed in a gap formed between the pot jacket and the inner pot of the enveloping pot and penetrating recesses, which are disposed in the inner pot of the enveloping pot and correspond to locking grooves in the outer pot of the product pot, a particularly effective connection between the product pot and the enveloping pot is made possible, the connection not being visible in the outer appearance of the pot and being easily detachable, if required.

Preferably, the locking element is designed as an annular spring element, which comprises spring protrusions, which penetrate recesses, which are disposed in a shared horizontal plane, in the inner pot of the enveloping pot and locking grooves in the outer pot of the product pot.

In another advantageous embodiment, the product pot is received in an inner pot of the enveloping pot, the enveloping pot comprising a pot collar formed independently of the inner pot and an outer pot, a first connection being provided between the pot collar and the inner pot and a second connection being provided between the pot collar and the outer pot.

Preferably, a pot weight is disposed in such a manner in a gap formed between the inner pot and outer pot that a lower edge of the pot weight is disposed on a pot bottom of the outer pot and an upper edge of the pot weight serves to both support an abutment edge of the inner pot and to support an abutment edge of the pot collar.

If an edge ridge, which is formed on the abutment edge of the pot collar and is oriented toward the pot bottom, is disposed in such a manner in an indentation realised on the abutment edge of the inner pot and corresponding to the edge ridge that a fully flush transition area from the edge ridge to the inner pot is realised on an inner side of the enveloping pot facing the product pot, a transition area unperceivable in the outer appearance of the pot is made possible between the different components.

Preferably, an abutment edge of the product pot is disposed on the abutment edge of the pot collar, the abutment edge of the product pot preferably comprising an edge ridge, which is spaced from the abutment edge of the pot collar, for forming a ring gap radially open outward.

If the product pot is received in the inner pot of the enveloping pot in a form-fit manner, a connection between the product pot and the enveloping pot can be created by this which is sufficient for the use of the pot.

Preferably, a force-fit radial material protrusion is formed between a pot wall of the inner pot and a pot wall of the product pot, meaning forming the clamping force becomes possible which additionally secures the connection between the product pot and the inner pot of the enveloping pot.

Advantageous embodiments of the invention are described in further detail using the drawing.

FIGS. 1 to 4 show a pot 20 which is realised in multiple parts and in the case of the illustrated exemplary embodiment has four components, namely a product pot 21, an enveloping pot 22, a pot collar 23 connecting the product pot to the enveloping pot and a pot weight 25 disposed in enveloping pot 22 in a gap 24 disposed between product pot 21 and enveloping pot 22.

On an upper collar edge 26, pot collar 23 is connected to an abutment edge 27 formed on the upper edge of product pot 21 and supports itself on pot weight 25, which is disposed in enveloping pot 22 and surrounds product pot 21 like a sleeve, by its lower edge 28.

The connection between pot collar 23 and enveloping pot 22 is provided on a ledge 30 extending around pot collar 23, the support of pot collar 23 on pot weight 25 by its support edge 28 achieving that a connective edge 29, which is formed on enveloping pot 22, is fully flush with a transition surface 31, which is formed by ledge 30.

As is derived from the explanations above, only two connections 31, 32, namely connection 32 realised between product pot 21 and pot collar 23 and connection 33 realised between pot collar 23 and enveloping pot 22, need to be executed for producing pot 20 as illustrated in FIGS. 1 to 4. Both connections 32 and 33 can be realised as either a press-fit connection, an adhesive connection or a welded connection. Moreover, another connection can be provided between enveloping pot 22 and pot weight 25, which can also be realised as either a press-fit connection, an adhesive connection or a welded connection.

As is discernible particularly from a synopsis of FIGS. 3 and 4, the relative arrangement of pot collar 23 in relation to enveloping pot 22 enables an orientation of the pot collar by means of pot collar 23 supporting itself on pot weight 25 disposed in enveloping pot 22, in particular enabling the fully flush arrangement between transition surface 31 and connective edge 29 of enveloping pot 22 as described above and moreover a simple adjustment of the contours of pot collar 23 to the contour of enveloping pot 22, without requiring an exact adjustment of the contour of support edge 28 of pot collar 23 to an abutment edge 35 of pot weight 25. Pot collar 23 and pot weight 25 can be connected in particular via adhesion or welding.

Enveloping pot 22 can therefore be provided with complex cross-sectional transitions in its contour, without requiring an adjustment of the contour of pot collar 23 to the contour of enveloping pot 22. In the case at hand, the contour of outer pot 22 is formed such that a circular cross section, which is formed on connective edge 29 of the outer pot, continuously transitions into a cross section which has changing radii and is formed on lower edge 34 of outer pot 22 in the transition to pot bottom 36.

The embodiment which is intended for pot 20 and is independent of the embodiment of product pot 21 and enveloping pot 22 moreover brings the advantage of a pot thread 37 formed on pot collar 23 being able to be produced in a separate forming process independently of product pot 21 and enveloping pot 22.

A pot 40 according to a second embodiment is illustrated in FIGS. 5 to 9.

As discernible in particular in FIG. 6, pot 40 is set up from a plurality of components, a synopsis of FIGS. 6 and 7 clearly showing that a product pot 42, which is received in an enveloping pot 41 and is designed as an exchangeable pot, is made up of an inner pot 43, an outer pot 44 and a pot collar 45 connecting inner pot 43 to outer pot 44.

In particular FIG. 8 shows that a first connection 46 for connecting inner pot 43 to pot collar 45 is formed between an upper opening edge 47 of inner pot 43 and a collar edge 48 of pot collar 45, and a second connection 49 is provided between an opening edge 50 of outer pot 44 and opening tabs 51 formed on the lower edge of pot collar 45.

Enveloping pot 41 comprises an inner pot 53 received in an outer pot 52, outer pot 52 being made up of a pot jacket 54 and a pot bottom 55. In this case, a first connection 56 is realised between an upper edge 57 of inner pot 53 and an opening edge 58 of pot jacket 54 and a second connection 59 is realised between a lower edge 60 of pot jacket 54 and connective tabs 61 disposed on pot bottom 55. Analog to connections 46 and 49, connections 56 and 59 can be realised as a press-fit connection, an adhesive connection or a welding connection.

Between product pot 42 and enveloping pot 41, a detachable connective to device 62 is provided which is realised as a locking connection and has a shape-elastic locking element which in the instance at hand is made of an annular spring element 63, whose shape is adjusted to the circumference of inner pot 53 of enveloping pot 41 and which rests snuggly against a pot wall 71 of inner pot 53 facing pot jacket 53 and is passed through a recess 65 in pot wall 71 with a total of four spring protrusions 64 in the instance at hand. In this context, recesses 65 are disposed in opposite sides of pot wall 71 in a horizontal connective plane 66.

As FIGS. 6 and 8 show, outer pot 44 of product pot 42 comprises locking grooves 68 in a connective plane 67 in an arrangement corresponding to recesses 65. If product pot 42 is inserted in enveloping pot 41, spring protrusions 64 of spring element 63 are pushed radially outward upon contact with a pot bottom 69 of product pot 42 and lock in locking grooves 68 when reaching a congruent arrangement of connective planes 66, 67 so that product pot 42 is detachably locked in enveloping pot 41. When exerting a tensile force exerted on pot collar 45 against the insertion movement, product pot 42 can be removed from enveloping pot 41 by overcoming the spring force of spring element 63.

As in particular FIG. 9 shows, locking grooves 70 corresponding to locking grooves 68 are provided on the upper edge of pot collar 45 so that a connective device corresponding to connective device 62 can be provided between a screw cap (not further illustrated) and pot collar 45 when the screw cap is designed according to the corresponding embodiment.

In FIGS. 10 to 13, a pot 80 is illustrated in another embodiment, pot 80 comprising a product pot 81 designed as an exchangeable pot and being received in an inner pot 82 of an enveloping pot 83. Enveloping pot 83 comprises a pot collar 84 formed independently to inner pot 82 and an outer pot 85, a first connection 86 being realised between pot collar 84 and inner pot 82 and a second connection being realised between pot collar 84 and outer pot 85.

Between inner pot 82 and outer pot 85, a gap 88 is formed in which a pot weight 89 is disposed. Pot weight 89, whose lower edge 90 is disposed on a pot bottom 91 of outer pot 85, comprises an upper edge 92, which serves on the one hand for supporting an abutment edge 93 of inner pot 82 and on the other hand for supporting an abutment edge 94 of pot collar 84.

On abutment edge 94, pot collar 84 is provided with an edge ridge 95, which is oriented toward pot bottom 91 and is received in an indentation 96 adjacent to abutment edge 93 of inner pot 82 and corresponding to edge ridge 95. Owing to this, a fully flush transition from edge ridge 95 to inner pot 82 is realised on an inner side 97 of enveloping pot 83 facing toward product pot 81.

As in particular FIG. 12 shows, an abutment edge 98 of product pot 81 is disposed on abutment edge 94 of pot collar 84, which belongs to enveloping pot 83, abutment edge 98 comprising an edge ledge 100, which is distanced from abutment edge 94 of the enveloping pot, for forming a ring gap 99 open radially outward.

As in particular a synopsis of FIGS. 10 and 11 clearly shows, product pot 81 is removably received in enveloping pot 83, ring gap 99 illustrated in FIG. 12 making it possible to grab edge ledge 100 formed on product pot 81 and to pull out product pot 81 from inner pot 82 of enveloping pot 83. As particularly shown in the exploded view of FIG. 13, a radial material protrusion 101 is formed on inner pot 82 of enveloping pot 83 for this purpose, material protrusion 101 enabling forming a radial clamping force between inner pot 82 of enveloping pot 83 and product pot 81, the clamping force requiring a defined tensile force for removing product pot 81, which is received in enveloping pot 83 in a form-fit manner, from enveloping pot 83 to prevent product pot 81 from sliding out unintentionally from enveloping pot 83.

Both connections 86, 87 mentioned above between pot collar 84 and inner pot 82 and outer pot 85 of enveloping pot 83 and a radial connection between pot weight 89 and pot collar 84 can be realised as a purely force-fit connection or alternatively or additionally as an adhesive or welded connection according to a corresponding interpretation, the pot weight being provided with a gap 102 illustrated in particular in FIG. 13 for the force-fit connection between pot weight 89 and pot collar 84 of the pot weight, gap 102 enabling an embodiment of sleeve-shaped pot weight 89 in the manner of a spring sleeve so that a pre-tension force is formed between pot collar 84 and pot weight 89 on the circumference of pot weight 89.
